Slugs are very efficient in the use of their body parts. The mantle encloses and protects the slugs internal organs, pumps water and filters out food, and stores eggs while they mature. The body is primarily made up of water to avoid desiccation.

2020年2月25日 · Mobile tracking of large terrestrial PIT-tagged slugs using portable and stationary antennas may prove an important tool to investigate dispersal, movements between feeding and sheltering habitats and potential homing behaviour.

In this study, a new microstrip-antenna-based microwave transmission sensor (MAMTS) and a new decoupling method are proposed to achieve salinity independent measurement of water holdup in oil-gas-water slug flows.

We selected three species of slug moth (Narosoideus flavidorsalis, Chalcoscelides castaneipars, and Setora postornata) with different diet breadths to detect the structural diversity of antennal sensilla using the scanning electron microscope.

2012年8月30日 · Ferrite rods, bars, slugs, plates and tubes are primarily used as magnetic cores in radio antennas, chokes, inductors and filters. In radio antennas, ferrite rods are useful from VLF spectrum to VHF spectrum. The advantages are small size, high Q and compactness. Ferrite rods and bars are available in standard lengths up to 12" long.

2019年5月12日 · Is it practical to use a slug-tuned variable inductor in an antenna matcher (aka “antenna tuner”)? As far as I have been able to determine after countless exhaustive searches, I believe that the answer is no. While trying to minimize costs is certainly an admirable goal, I think that you should abandon this idea for a proven design.

2020年2月10日 · This very much sought-after radio is a well engineered ‘double-tuned’ set utilizing a series-tuned antenna tank circuit coupled to a parallel-tuned detector tank. Both coils are wound on the same 1/4” diameter tubular form containing two ferrite slugs ...

Field tuning ERI (and other slug-tuned) FM broadcast antennas. This is essentially an expanded abstract. Although incomplete, this note identifies the elements involved in slug tuning well enough that most RF engineers can get through the procedure with some experimentation.

2011年7月10日 · My preferred type of antenna for operation on the upper HF bands is the end fed half wave. They perform well and don't need radials. This type of antenna has been described well by AA5TB and also in RadCom. Supporting the …

Slugs and snails have two pairs of tentacles or antennae that act as sensory organs, much like your eyes, nose, and tongue. The two longer upper tentacles are used for seeing and smelling the world around them. The two shorter lower tentacles are used for smelling and tasting.
